DISPLAY ADVERTISING MECHANISM.

Patented Mar. it, fillet. Serial No. 760,667.

To all coho/1t it may concern.

Be it known that 1, DAVID H. Warm. a citizen of the Dominion of Canada, residing at Vancouver, in the Province of Brit-- ish Columbia, Canada, have invented certain new and useful Improvements in Dis play Advertising Mechanisms, of which the following is a specification.

This invention relates to an advertising display mechanism of that class which is exempliiied in my Patent $21,063,? issued June 8, 1913 and the improvement comprises a modification and amplification of the system there set forth whereby a greater space is available for advertising display.

The invention comprises mainly the use of a sheet folded lengthwise and attached at the fold to the flanges of the reel on which the sheets are carried; by which manner of attachment the action of one half of the sheet, when it falls from the confinement of the casing in which the reel is mounted, displays an area corresponding to the entire width of the sheet, or approximately double the folded width, as retained within the casing.

The invention also comprises the manner of attachment to the sheets of the loops by which the folded sheets are pivotally con nected to the flanges of the reel, and to the construction of the reel flanges whereby the attachment of the loops is facilitated.

The invention is particularly described in the following specification, reference being made to the drawings by which it is accompanied, in which:

Figure 1 is a perspective view of one of the folded sheets showing its attaching loops at the lengthwise fold. Figs. 2 and are enlarged details in perspective showing the manner of attachment of the reel connecting loop to the sheet, and of the edges of the flanges of the reel to which these loops are connected, and Fig. at is a cross section showing the manner in which the sheets fold within the casing and fall open at the exposure aperture of the casing. Fig. 5 is a detail cross section of a part of the invention. Fig. dis a detail section of the modification hereinafter referred to.

In these drawings 2 and '3 represent the two parts of a display sheet which is folded lengthwise at 4 along the connection of the sheets to the flanges 55 of the reel. At intervals along the fold 4 loops 6 of thin resilient wire are connected to thetwo parts notches 12.

2 and 3 of the sheet, the attachment being preferably by means of a flexible tape or strip 7, a loop 8 of which is passed through a slit 9 in the fold t of the sheets with the cross bar of the loop (3 in the loop 8 of the strip where it is inserted. The two ends of this strip 7 are passed through slits 10 a. short distance from the fold i and these ends of the tape are cemented or otherwise secured to the outer faces of the sheet on each side. The reel to which these display sheets 2-3 are connected is composed of a series of flanges each made up of two thin metal disks or rings 5, which are secured together through distance pieces 15 at a space apart corresponding to the width of the loop 6. These flanges are secured at intervals apart on a common shaft 16 which shaft is rotatably mounted in bearings within a ca sing 17. Around the periphery of these disks 5 are notches 12 and a short distance from the edges are apertures 13. into the apertures 13 the inwardly turned ends 11 of each loop 6 are sprung and the cross bar of the loop adjacent to the bends rests in the 30 mounted across the reel flanges the sheets are free to fold and unfold and may bend around the periphery of the reel flanges to lie within the casing and will fall freely over on their fold a and on their flexible connection to the loops 6. The body of this casing 17 is concentric with the flanges of the reel throughout about onehalf of the circumference from the upper edge of an exposure aperture 18, and the lower part curves away from the lower edge of the exposure aperture in a reverse curve, as at 19, which flare will receive the dis play sheets when folded again and will turn them gradually on their flexible con nections and bend them into the concentric portion of the casing 17, release from which curvature enabled them to spring out and fall open to expose the advertisements on their faces. To facilitate the movement of these folded sheets within the casing rollers 20 may be introduced at intervals within the casing parallel to the axis of rotation of the reel which will hold the sheets from frictional contact with the inside of the casing.

In use the reel, to the periphery of which the sheets 2-3 are flexibly connected, is rotated by any suitable mechanism that will impart either a slow continuous movement or an intermittent movement to it, and as the outer edge of the larger part 3 of each folded sheet escapes from the restraint of the casing 17 at the upper edge of the exposure aperture 18, it falls over, and as the edge of the smaller part 2 of the next sheet is within the edge of the greater part 3 of the preceding sheet, the smaller part 2 of the next sheet is also free from control and falls over with it, so that the movement that releases the last part of one sheet reveals the next sheet in full exposure. This is regarded as an important feature of the in vention and enhances its value as an advertising means, as it induces an observer to pause and consider how the effect is produced of exposing the full area of each folded sheet with one movement.

Although important, the invention is not tied up in this feature of unequal folding of each sheet to obtain full exposure of succeeding sheets, as the use of folded sheets equally divided is also an advantageous arrangement, in which case each part of each folded sheet is successively released and the exposure of both faces of each part of each sheet is obtained.

Although the sheets have been described and illustrated as folded into two parts 2 and 3, it is obvious that these parts may be distinct and flexibly connected together along the fold line 4;, as at 4:", see Fig. 6.

Having now particularly described my invention, I hereby declare that what I claim as new and desire to be protected in by Letters Patent, is:

1. A mechanical means for the display of advertisements or the like, said means comprising the combination with a casing, a reel or drum rotatably mounted within said casing, said casing having an exposure aperture along the front, of a series of sheets folded lengthwise, and means for flexibly connecting these sheets at the fold to the reel or drum.
